Currently, on device detach, we parse given XML, find the device
in domain object, free it and try to restore security labels.
However, in some cases (e.g. usb hostdev) parsed XML contains
less information than freed device. In usb case it is bus & device
IDs. These are needed during label restoring as a symlink into
/dev/bus is generated from them. Therefore don't drop device
configuration until security labels are restored.
The qemu RBD driver needs access to the conn in order to get the secret
needed for connecting to the ceph cluster.

If the daemon is restarted so we reconnect to monitor, cdrom media
can be ejected. In that case we don't want to show it in domain xml,
or require it on migration destination.
To check for disk status use 'info block' monitor command.
This patch enables modifying network device configuration using the
virUpdateDeviceFlags API method. Matching of devices is accomplished
using MAC addresses.
While updating live configuration of a running domain, the user is
allowed only to change link state of the interface. Additional
modifications may be added later. For now the code checks for
unsupported changes and thereafter changes the link state, if
applicable.
When updating persistent configuration of guest's network interface the
whole configuration (except for the MAC address) may be modified and
is stored for the next startup.
* src/qemu/qemu_driver.c - Add dispatching of virUpdateDevice for
network devices update (live/config)
* src/qemu/qemu_hotplug.c - add setting of initial link state on live
device addition
- add function to change network device
configuration. By now it supports only
changing of link state
* src/qemu/qemu_hotplug.h - Headers to above functions
* src/qemu/qemu_process.c - set link states before virtual machine
start. Qemu does not support setting of
this on the command line.
* src/conf/domain_conf.c, src/conf/domain_conf.h: APIs for
inserting/finding/removing virDomainLeaseDefPtr instances
* src/qemu/qemu_driver.c: Wire up hotplug/unplug for leases
* src/qemu/qemu_hotplug.h, src/qemu/qemu_hotplug.c: Support
for hotplug and unplug of leases
The way to detach a USB disk is the same as that to detach a SCSI
disk. Rename this function and we can use it to detach a USB disk.

This is done for two reasons:
- we are getting very close to 64 flags which is the maximum we can use
with unsigned long long
- by using LL constants in enum we already violates C99 constraint that
enum values have to fit into int
We try to use that command first when setting a VNC/SPICE password. If
that doesn't work we fallback to the legacy VNC only password
Allow an expiry time to be set, if that doesn't work, throw an error
if they try to use SPICE.
Change since v1:
- moved qemuInitGraphicsPasswords to qemu_hotplug, renamed
to qemuDomainChangeGraphicsPasswords.
- updated what looks like a typo (that appears to work anyway) in
initial patch from Daniel:
- ret = qemuInitGraphicsPasswords(driver, vm,
- VIR_DOMAIN_GRAPHICS_TYPE_SPICE,
- &vm->def->graphics[0]->data.vnc.auth,
- driver->vncPassword);
+ ret = qemuInitGraphicsPasswords(driver, vm,
+ VIR_DOMAIN_GRAPHICS_TYPE_SPICE,
+ &vm->def->graphics[0]->data.spice.auth,
+ driver->spicePassword);
Based on patch by Daniel P. Berrange <berrange@redhat.com>.
The QEMU driver file is far too large. Move all the hotplug
helper code out into a separate file. No functional change.
* src/qemu/qemu_hotplug.c, src/qemu/qemu_hotplug.h,
src/Makefile.am: Add hotplug helper file
* src/qemu/qemu_driver.c: Delete hotplug code
